Izimbangela kanye nokuhlaziywa kwemishini kokuchezuka kwebhande le-conveyor yebhande

I-belt conveyor iyithuluzi eliyinhloko lesistimu yokudlulisa, futhi ukusebenza kwayo okuphephile nokuzinzile kuthinta ngokuqondile ukunikezwa kwezinto zokusetshenziswa. Ukuphambuka kwebhande kuyiphutha elivame kakhulu le-conveyor yebhande , futhi ukwelashwa kwayo okufika ngesikhathi futhi okunembile kuyisiqinisekiso sokusebenza kwayo okuphephile nokuzinzile. Kunezimo eziningi kanye nezimbangela zokuphambuka, futhi izindlela zokulungisa ezihlukene kufanele zamukelwe ngokwezimo ezahlukene kanye nezimbangela zokuphambuka, ukuze kuxazululwe ngempumelelo inkinga. Leli phepha lisekelwe eminyakeni eminingi yokuzijwayeza yasensimini, ngokombono womsebenzisi, kusetshenziswa isimiso se-mechanics ukuhlaziya nokuchaza izimbangela zokwehluleka okunjalo nezindlela zokwelashwa.

1. Iphutha lokuma phakathi kwendawo yokufaka ye-idle ephethe kanye nolayini omaphakathi wesithumeli mkhulu, okuholela ekutheni ibhande ligijime liphambuke esigabeni esithwalayo . Uma ibhande ligijimela phambili, linikeza i-roller amandla okuhamba phambili okuhamba phambili i-Fq, ehlukaniswa ibe ingxenye yamandla Fz eyenza i-roller ijikeleze kanye nengxenye ye-lateral force Fc eyenza i-roller axial movement. Njengoba i-roller elungiswe uhlaka olungenzi lutho lungakwazi ukuhamba nge-axially, nakanjani izokhiqiza amandla okusabela i-Fy ebhandeni, okwenza i-blet ihambe iye kolunye uhlangothi, okuholela ekuphambukeni.

Ngemuva kokucacisa ngesimo samandla sokuphambuka kokuthwala i-idler ngemuva kokufakwa, akunzima ukuqonda izizathu zokuchezuka kwebhande, indlela yokulungisa nayo icacile,Indlela yokuqala ukucubungula izimbobo ezinde ezinhlangothini zombili zesethi ye-idler. ukuze kulungiswe .Indlela eqondile iwukuthi iluphi uhlangothi ibhande elisuswayo, futhi uhlangothi lwevila kufanele luye phambili lapho ibhande libheke khona, noma olunye uhlangothi kufanele luhlehle . Uma ibhande ligijima liye phezulu, indawo ephansi yomuntu ongenzi lutho kufanele ihambe iye kwesokunxele, futhi indawo engaphezulu yevila kufanele iye kwesokudla.

Indlela yesibili ukufaka amavila okuqondanisa, amavila okuqondanisa anezinhlobonhlobo zezinhlobo, njengohlobo lweshaft emaphakathi, uhlobo lwezixhumanisi ezine, uhlobo lwamarola aqondile, njll. Umgomo uwukuvimba noma ukuzungeza okungenzi lutho kuhlangothi lwendiza oluvundlile ukuze uvimbele. noma ukhiqize i-transverse thrust ukuze lenze ibhande libe phakathi nendawo ngokuzenzakalelayo ukuze kufezwe injongo yokulungisa ukuchezuka kwebhande, futhi isimo salo sokucindezeleka siyefana nesomuntu ongenzi lutho ophethe . Ngokuvamile, le ndlela inengqondo kakhulu uma ubude bebonke bomthumeli webhande bufushane noma lapho isihambisi sebhande sisebenza kuzo zombili izinkomba, ngoba i-conveyor yebhande elifushane kungenzeka ukuthi libaleke futhi akulula ukulilungisa. Le ndlela ku-conveyor yebhande elide kungcono ukuthi ingasetshenziswa , ngoba ukusetshenziswa kokuqondisa i-idler kuzoba nomthelela othile empilweni yesevisi yebhande.

2. I-axis yekhanda elishayela i-pulleyor tail returningpulley ayiyona i-perpendicular to the center line of the conveyor, okubangela ukuthi ibhande ligijime kusigubhu esiyinhloko noma isigubhu esihlehlisa umsila. Lapho i-pulley ichezuka, ukuqina kwebhande ezinhlangothini zombili ze-pulley akuhambisani, futhi amandla okudonsa i-Fq atholwe eceleni kobubanzi bokuqondisa akuhambisani, okuba umkhuba okhulayo noma owehlayo, okuzokwenza ibhande linamathisele amandla ahambayo. I-Fy in the direction ehlayo, okuholela ekutheni ibhande libaleke ohlangothini oluvulekile, okungukuthi, lokho okubizwa ngokuthi "ukugijima okuxekethile kodwa hhayi ukugijima kuqinile".

Indlela yokulungisa imi kanje: ku-pulley yekhanda, uma ibhande ligijima liye kwesokudla se-pulley, i-pillow block kufanele iqhubekele phambili. kufanele iye phambili, futhi umcamelo wesokunxele ohambisanayo nawo ungabuyiselwa emuva noma umcamelo wesokudla ubuyiselwe emuva. Indlela yokulungisa i-pulley yomsila iphambene ncamashi ne-pulley yekhanda. Ngemuva kokulungiswa okuphindaphindiwe kuze kube yilapho ibhande lilungiswa endaweni ekahle. Kungcono ukufaka i-idler ngokunembile ngaphambi kokulungisa idrayivu noma i-pulley ebuyayo

Okwesithathu, ukubekezelelana okungalungile kwendawo yangaphandle ye-pulley, izinto zokunamathisela noma ukugqoka okungalingani kubangela ukuthi ububanzi buhluke, futhi ibhande lizogijima libheke ohlangothini ngobubanzi obukhulu. Yilokho okubizwa ngokuthi "gijima omkhulu ungagijimi omncane". Isimo salo samandla: amandla adonsela phansi i-Fq yebhande enza amandla ashukumisayo e-Fy abheke ohlangothini olukhulu lobubanzi, esenzweni se-force force Fy, ibhande lizoveza ukuchezuka. Kulesi simo, isixazululo ukuhlanza izinto ezinamathelayo ngaphezulu kwesigubhu, indawo ebambekayo ene-mismachining tolrence kanye nokugqoka okungalingani kufanele kushintshwe futhi kucutshungulwe kabusha ukushesha kwenjoloba.

Okwesine, iphoyinti lokudlulisa endaweni yokulahla impahla aliqondile ukuze libangele ukuchezuka kwebhande. iphoyinti lokudlulisa lempahla endaweni yokulahla impahla ekuchezukeni kwebhande linomthelela omkhulu kakhulu, ikakhulukazi ukuqagela kwama-conveyor amabili emhlabathini ovundlile kuye kwame mpo, umthelela uzoba mkhulu kakhulu. Ngokuvamile ukuphakama okuhlobene kwamabhande amabili ngenhla nangaphansi endaweni yokudlulisa kufanele kucatshangelwe. Ukuncipha kobude obuhlobene, kuyanda ingxenye yesivinini evundlile yezinto ezibonakalayo, kuba mkhulu umthelela ongaseceleni we-Fc ebhandeni eliphansi, futhi okubalulekile nakho kuba nzima ukumisa phakathi nendawo. Izinto ezisesigabeni esiphambanayo sebhande ziyaphambuka, futhi ingxenye evundlile yamandla omthelela we-Fc Fy ekugcineni ibangele ukuthi ibhande libaleke. Uma impahla iya kwesokudla, ibhande liya ngakwesobunxele, futhi ngokuphambene nalokho.

Ngokuphambuka kulokhu, ukuphakama okuhlobene kwama-conveyors amabili kufanele kukhuliswe ngangokunokwenzeka phakathi nenqubo yokuklama. Ifomu kanye nosayizi wamafaneli angaphezulu naphansi kanye nama-chute aqondisayo okuthutha amabhande anemikhawulo yesikhala kufanele kucatshangelwe ngokucophelela. Ngokuvamile, ububanzi bama-chute omhlahlandlela kufanele bube yizingxenye ezintathu nesihlanu zobubanzi bebhande. Ukuze kuncishiswe noma kugwenywe ukuchezuka kwebhande, ipuleti le-baffle lingangezwa ukuze livimbe into futhi lishintshe indlela kanye nesimo sento.

Okwesihlanu. Izinkinga zebhande ngokwalo. njengokusetshenziswa kwebhande isikhathi eside, ukuguga ukuguga, ukuguga konqenqema, noma isikhungo sokuhlangana kabusha asiqondile ngemuva kokulimala kwebhande, okuzokwenza ukungezwani ezinhlangothini ezimbili zebhande kungahambisani futhi kuholele ekutheni ukuchezuka. Kulesi simo, ubude bebhande lonke buzogijima ohlangothini olulodwa, futhi ukuphelelwa okukhulu kuhlangene okungalungile. Indlela kuphela yokubhekana nayo ukwenza kabusha i-rubber ehlangene nesikhungo esingalungile, futhi esikhundleni sokuguqulwa kokuguga kwebhande.

Okwesithupha, idivayisi ye-tension ye-conveyor ayikwazi ukwenza i-enouth tension force ebhandeni. ibhande aliphambuki ngaphandle komthwalo noma inani elincane lomthwalo , lapho umthwalo ukhulu kancane kuzoba khona ukuphambuka. Idivayisi ye-tension iyisisetshenziswa esisebenzayo sokuqinisekisa ukuthi ibhande lihlala ligcina amandla anele okucindezela. Uma amandla okucindezela akwanele, ukuzinza kwebhande kubi kakhulu, umthelela omkhulu wokuphazanyiswa kwangaphandle, futhi umcimbi wokushelela uzokwenzeka ezimweni ezimbi kakhulu. Kwabathumeli bebhande abasebenzisa amadivaysi okucindezela isisindo, ama-counterweights angangezwa ukuze axazulule inkinga, kodwa akumele afakwe kakhulu, ukuze angenzi ibhande lebhande licindezeleke ngokweqile futhi linciphise impilo yesevisi yebhande. Kwabathumeli bebhande abasebenzisa i-spiral noma i-hydraulic tension, i-tension stroke ingalungiswa ukuze kwandiswe amandla okucindezela. Kodwa-ke, ngezinye izikhathi ukushaywa kwe-tension akwanele futhi ibhande likhubazekile unomphela, ngaleso sikhathi ingxenye yebhande inganqunywa futhi iboshwe kabusha.

Okwesikhombisa, ku-conveyor webhande ngokuklama kwe-concave, njenge-radius of curvature yesigaba se-concave incane kakhulu, uma kungekho lutho ebhandeni lapho uqala, ibhande lizovela esigabeni se-concave, esimweni. isimo sezulu esinamandla somoya sizophinde sishaye ibhande, ngakho-ke, kungcono ukwengeza isondo lebhande lokucindezela engxenyeni ye-concave ye-conveyor yebhande ukuze ugweme isiphethu sebhande noma ukushaywa umoya.
